FIRING MECHANISM FOR GUNS.

. Appncatioaniea :ruiy 26,

To all w /Lom may conce/m Be it known that I, EUGENE SCHNEIDEN, a citizen oi' the Republic of France, residing at 42 Rue dAnjou, Paris, France, have invented new and useful Improvements in Firing h/ilechanisms for Guns, which is fully set forth in the Yfollowing specification. Q

This invention consists 1n vario-us improvements on the invention of the irlng mechanism composed of a combined strikercarrier and tiring tube holder for t-he breech mechanism oi guns for which a patent was sealed under No. 1,810,887,

The present improvements are illustrated in the accompanying drawings in which F ig. l is a sectional elevation along the axis of a striker-carrier combined with a firing tube holder'.

tig. 2 is a front elevation showing the tiring tube holder lifted up to allow ot the insertion of a new ring tube.

Fig. 3 is a developed section on the line 3 3 of Fig. e.

This improved constructional form is characterized by the feature that the pivot pin C, by means of which a disc A constituting the firing tube holder proper is plvoted to the body B of the striker-carrier, instead of being fixed, that is to say attached to the said body B, is movable longitudinally in the latter in such a` manner as to be -capable of projecting from the striker-carrier to an extent that varies according to the thickness of the base of the firing tube.

A spring D assures nevertheless in all cases a perfect bearing of the tiring tube against the body of the striker-carrier.

It will be readily understood that it' the tiring tube E were to be replaced by a new firing tube whose base c would be slightly thicker than that of the tiring tube that has just been removed, the bearing ot' the new tiring tube would be perfectly assured at the cost ot' a simple supplementary pressure of the spring D.

This arranvenient ot spring pivot C-D which is movable longitudinally allows on the other hand of simplifying the mounting of the disc A upon the body of the strikercarrier. For this purpose it is suilicient to provide the lodgment for the base e in the disc A in such a manner that in all cases the said base shall project to the rear of the disc, and to provide on the other hand in the body B of the striker-carrier a central recess b 1921. Serial No. 487,681.

adapted to receive the said projection of t-he base of the tiring tube.

In the rotational movement which is imparted to the disc A in order to bring the new firing tube, which has just been inserted inthe said disc, into its operative position, the projection or' the base oi the tiring tube strikes a chamfer 1 over which it slides and thereby detachee the disc A slightly from the striker-carrier B, compressing for this purpose the spring D. Then the said projection of the base enters the recess b, and the sprin D expands and thus assures the bearing 0% the firing tube upon the said body B of the striker-carrier.

In order that the movement of raising the disc A for the purpose of removing the firing tube, shall be easily effected, a chamfer b2 is formed on the edge of the recess I claim l. A tiring mechanism for guns comprising, in combination, a striker-carrier, apivot pin slidably mounted in said carrier, a firing-tube holder eccentrically pivoted to said striker-carrier by means ot said pin, and a spring operatively engaging said pin and tending to move said pin rearward relative to said striker-carrier.

2. A firing mechanism for guns comprising, in combination, a striker-carrier having a recess in one rend thereof, a pivotv member resiliently mounted in said striker-carrier, and a tiring-tube holder carried by said member, said recess being adapted to receive the base of a firing tube whereby angular movement of said holder is prevented.

3. A firing mechanism for guns comprising, in combination, a striker-carrier, a pivot pin slidably mounted in said striker-carrier, a tiring-tube holder eccentrically mounted on said pin and having angular movement relative to said striker-carrier, and a spring normally tending to move said holder rearward relative to said striker-carrier.

4. In a firing mechanism for guns, the combination of a striker-carrier having a chamfer at one end thereof, a tiring tube holder' pivoted thereto, to swing transverse tothe axis of said carrier, and a pivot pin resilient-ly mounted in said striker-carrier for supporting said holder, said chamfer being positioned in the arcuate path of said holder.

5. In a firing mechanism for guns, the combination of a striker-carrier having a chamiter and u. ehumfered recess in one end thereof, en element mounted in the strikerearrier for relative longitudinal movement thereto, and e firing tube holder carried by said element, said chamfer and chamfered recess being adapted to facilita-te the placing of e tiring tube in firing position.

6. In a device of the class described, a striker-carrier, a, pivot pin mounted in said strikercarrier for relative longitudinal movement thereto, a resilient member positioned to eoact With the pivot pin and :L i1 ing tube holder carried by said pin.

In testimony whereof I have signed this speciication.

EUGENE, SCHNEIDER.
